To aZZ' whom t may concern: 1

Beit known that I, WILLIAM B. KIRKPAT- RICK, a citizen of the United States, residing at Canton, in the county of Stark and State of Ohio, have invented certain new and use- 'ful Improvements in Hay-Loaders; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, and to the figures of reference marked thereon, in which- Figure l is a perspective view.

i The present invention has relation to hayloaders; and it consists in the different parts and combination of parts hereinafter described, and particularly pointed out in the claim.

Similar numbers of reference indicate corresponding parts in all the iigu res of the drawings.

In the accompanying drawings,'1 represents the traveling Wheels, which are mounted upon the axle 2 in the usual manner, to which axle are attached the upright bars or supports 3 and the rearward-extending bars 4, to which the side pieces or members are attached in the usual manner.

To the rear ends or portions of the bars 4 are connected slotted uprights 5 and 6, said uprights being preferably formed integral with the plate or bar 7.

To the uprights 6 are adj ustably attached 1 the compound crank-shaft bearings 8, said bearings being located substantially as shown in Fig. 5. The compound crank-shaft 9 is located serai No. 670,000. (No man.)

transversely across the bottom or lower portion of the frame proper and to Whichcompound shaft the rake-bars 1Q are journaled in the usual manner.

Below the rake-bars 10 are located the slats 11, which slats are supported upon the cross or tie bars 12. To the bottom or lower ends of the rake-bars 10 are connected the rakeheads 13, which rake-heads are provided with the teeth 14.

To the side members are attached the uprights or posts 16, which uprights or posts are provided with the slots. 17, through which slots are passedthe clamping-bolts 18, said clamping-bolts being for the purpose of holding the cross-bars 19, which cross-bars are located substantially as shown in Fig. 1.

To the cross-bars 19 are attached the guides and supports 20, said guides-and supports being. located and arranged substantially as shown in Fig. 1 and are for the purpose of holding and guiding the top or upper ends of the rake-bars 10, as hereinafter described.

To the top or upper ends of the rake-bars 10 are attached the arms'2l, to which arms are journaled the rollers 22, said rollers resting upon the top faces of the guides 20, as illustrated in the drawings.

Between the cross-bars 19 are located the rollers 23, which rollers are journaled to the brackets 24, said brackets being securely attached to the guides 2O or. their equivalents.

For the purpose of providing a means for moving the cross-bars 19 to or from the slats 11 said cross-bars are adjustably connected to the posts 16 by means of the clamping-l bolts 18. l

It will be understood that as the cross-bars 19 are moved in either direction they will carry with them the guides 20, thereby providing a means for adjusting the space between the slats and the rake-bars 10, therebyT providing for the proper handling of dierent kinds of hay.

When it is desired to change the adjustment of the cross-bars 19, together with the different parts connected to said cross-bars,

the clamping-bolts are released, after which the cross-bars are free to be moved up or down, as desired, and when brought to the desired point of adjustment said clamping-bolts are tightened.

For the purpose of adjusting the compound crank-shaft 9 to or from the slats 11, together with the rack-bars journaled thereto, the bearings 8 are adjustably attached to the slotted uprights 6, said bearings being held at the desiredpoint of adjustment by means of clamping-bolts 25, which clamping-bolts are passed through the slots 26.

For the purpose of causing the compound crank-shaft to be rotated in the opposite direction from that of the traveling-wheels l the driving-chains are carried under the sprocket-wheels 27 and around the idlers 28, said idlers being located at the rear of the sprocket-wheels 27 and being journaled upon the shafts or spindles 29, which spindlesare carried by the bearings 30, said bearings being adjustably connected to the posts or uprights 5 and being held at the desired point of adjustment by means of the clampingbolts 3l.

For the purpose of moving the bearings 8 and 30 in unison the connecting-bars 32 are provided, which bars are attached to the bolts holding the bearings. To the top or upper ends of the posts or uprights 5 are pivotally attached the levers 33, which levers are connected to the connecting-bars 32, substantially as shown in Fig. 5, and when it is desired to elevate the bearings, so as to change the position of the crank-shaft with reference to the slats 1l, the bearings are loosened and the rear ends of the levers 33 pressed downward until the bearings have been brought to the required height, after which the clamping-bolts are tightened.

It will be understood that by means of my peculiar arrangement I am enabled to adjust both the lower and upper ends of the rakebars 10, together with their teeth 34, to or from the slats ll, or change the angularity of said rake-bars with reference to the slats, thereby providing for the proper handling or elevating of various `kinds of hay.

For the purpose of providing a means for connecting the hay-loader proper to the rear end of a wagon the tongue 35 is.provided, which tongue is pivotally attached to the axle 2, said tongue being provided with the ordinary lateral braces 3G, said braces being attached in the ordinary manner. To the top or upper side of the tongue 35 is connected the plate 37, which plate is provided with the slots 38, which slots are for the purpose of receiving the lower portions of the supporting-bars 39, said supporting-bars being pivotally connected to the bar 40, which bar is securely attached to the tie-bars upon which the slats Il are attached.

Upon the bars 39.is located the sliding head 4l, to which sliding head is connected the clamping-bar 42, which clamping-bar is for the purpose of binding the sliding head, so as to hold the same at the desired point of adjustment by means of the screw-threaded bar 43 and the bar 42.

For the purpose of providing a means for yieldingly holding the hay-loader frame in the desired position the spring 45 is provided,

which spring is located around the bar 4G, which bar is Vconnected to the tongue 35 and extends through the sliding head 4l, substantially as shown in Fig. 8.

For the purpose of changing the position of the top or upper ends of the bars 39 the bar 40 is provided With a series of apertures such as 47, said apertures being for the purpose of bringing the supporting-bars to or from the top or upper end of the hay-loader frame proper.

It will be understood that when the rakebars 10 are forced upward at their upper ends they will come in contact with the rollers 23, thereby reducing the friction of said rakebars and allowing free movement of said bars.

For the purpose of providing a means for conveying the hay to the extreme upper end of the frame, the lpivoted apron 48 is provided and is pivotally attached to the side members l5 or their equivalents and when not in use remains in the position illustrated in Figs. l and 2.

When it is desired to hold the apron in an elevated position, the bar 49 is engaged with the spring-bars 50,said spring-bars being provided with the apertures 51, through which apertures the ends of the bar 47 are passed, it being understood that the bars 50 are to be sprung outward when it is desired to connect the bar 49.

The object and purpose to provide springbars, such as 50, is to prevent any accidental displacement of the apron.

For the purpose of providing a means for imparting rotary motion to the compound crank-shaft 9 the sprocket-Wheels 52 are pro vided and are mounted upon the axle 2 in the ordinary manner--that is to say, so that they can be thrown into andout of gear-Which con'- struction is common and does not need to be explained and forms no part of the present invention that such wheels must necessarily be provided.

For the purpose of properly connecting the rear ends of the bars 4 together the cross-bar 53 is provided, which is connected to the rear ends of said bars 4, substantially as shown in Fig. 1.

If desired, the bar or brace 53 may be attached to the top or upper ends of the uprights 5, it being understood that said uprights may be extended, so to provide a means for attachment. Y

In Fig. 5v the brace or bar 53 isl not shown; but it will be understood it is to be connected to the rear end of the bar 4, (shown in said gure,) or, as above stated, it may be attached to the top or upper end, as desired.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

In a hay-loader the combination of a traveling frame, drive-chains extended rearward and under the compound crankshaft-propelling sprocket-wheels, and over idlers, a com- IOO los
